2. Figure 1
Identification of space-time landmarks from the pressure iso-contour plot that was used for AIM analysis by AIMplot. An example 10-mL liquid bolus in a control subject is shown. For illustrative purposes, a radiologic image shows the position of the velopharynx (VP) during swallow outlined in yellow. From the manometric plot, the position of the velopharynx is identified by the pressure zone immediately proximal to the propagated pharyngeal pressure wave. Note: observers did not refer to radiologic images when performing analysis with AIMplot.

5. Figure 4
Example pressure iso-contour plots from database swallows showing the identification of the 3 space-time landmarks that are used for AIM analysis. Dots (○) identify time of swallow onset, the position of the UES proximal margin after swallow, and the position of the velopharynx.
